I've a website which sometimes timeout with the exception in the bottom of my post.

The trees and menus in Umbraco wont load when I experience the problem, but the problem is fixed, when I recycle the website.

Has somebody experienced the same, and did you find a permanent fix for this?

The website is a 10.3.1
